TOKYO (AFP) - Japan's Toshiba has slapped South Korean rival SK Hynix with a lawsuit seeking damages claiming that it received sensitive trade secrets from a Japanese engineer.

The civil suit, which Toshiba announced late on Thursday, came as the Japanese police took 52-year-old Mr Yoshitaka Sugita into custody for allegedly copying sensitive research data for Toshiba's NAND-type flash memory and then handing it to its rival.

Mr Sugita had formerly worked for Toshiba partner SanDisk, which helps make the key technology - used in smartphones and digital cameras - and later passed it to his new employer Hynix. He no longer works for the South Korean company.

"Toshiba filed the suit on learning that a former employee of SK Hynix has been arrested in Japan for alleged criminal infringement of the Unfair Competition Prevention Act," it said in a statement.
